![]() To cover these frequency bands, the dual-band and multiband antennas are much desired with favorable characteristics such as compact size, low cost, and easy integration with the RF circuit. Many extensive explorations have been carried out including dipole, slot, and microstrip antennas. The higher band is also applied for 5G WiFi. The IEEE 802.11 wireless local area network (WLAN) standards have been used worldwide in these bands of 2.4∼2.4835, 5.15∼5.35, and 5.725∼5.875 GHz. The proposed solar cell antenna can provide a dual-band performance with the ability of DC power generation, which can be a potential candidate for future green low-carbon communication. The measurement results show that the lower band is from 2.27 to 2.5 GHz with an omnidirectional radiation pattern and the upper band is from 4.8 to 6.9 GHz with a directional radiation pattern. The slot and microstrip antennas are incorporated into the compact structure and multiple resonant modes are utilized for dual-band performance. ![]() The solar cells can act as a director for the lower band, and the main radiation structure for the higher band. Thirty solar cells are adopted and integrated into the antenna structure for both energy harvesting and wireless communication. The Tianjin Key Laboratory of Imaging and Sensing Microelectronic Technology, School of Microelectronics, Tianjin University, Tianjin, ChinaĪ single-port dual-band antenna integrated with solar cells is reported for the 2.4/5-GHz wireless local area network (WLAN) applications. ![]()
